Synthesis and Characterization of Co Complexes Coordinated by a Tetraanionic Bis(amidateanilido) Ligand.

ABSTRACT: The synthesis and characterization of a square planar Co^II complex coordinated by the tetraanionic bis(amidateanilido) L^4- ligand, 1^2-, and its corresponding one-electron oxidized forms 2^-, 3, and 4⁺ are discussed herein. 1^2- undergoes aerobic oxidation to form 2^-, a square planar S = 1 Co^III complex. This aerobic reactivity is attributed to a remarkably negative Co^II/Co^III potential, as observed in its cyclic voltammogram, which is among the most negative Co^II/Co^III couples reported. This supports the conclusion that the L^4- ligation is strongly stabilizing to the o
